Arthur Franck was born in Helsinki, Finland, in 1980, the son of journalist and documentary filmmaker Michael Franck. He studied at Arcada University of Applied Sciences in Helsinki, earning a Bachelor of Arts degree in 2009. Together with Sandra Enkvist, he co-founded the production company Polygraf Film. As a director, Franck has primarily worked in television, notably on the ten-part reality series "Soramonttuprinsessat" ("Gravel Pit Princesses," FI 2012), which follows twin sisters as they compete in folkracing for the first time.

His feature-length documentary "Olliver Hawk" (FI, 2019), about the renowned Finnish hypnotist Olavi Hakasalo, earned a nomination for Best Documentary at the Finnish Jussi Awards and took home Best Film at the Tampere Film Festival that same year. For television, he directed the three-part documentary "Sanningen enligt Hassan" (FI, 2021), which chronicles the story of Hassan Zubier—a man who became a hero during a terrorist attack in Finland but later made headlines for fraud. From 2019 to 2021, Franck served on the board of the Docpoint Film Festival.

In March 2025, Franck premiered his documentary "The Helsinki Effect," a Finnish-German-Norwegian co-production, at the Copenhagen festival CPH:DOX. The film explores the historic 1975 CSCE conference in Helsinki through archival footage, secret documents, and AI-generated voiceovers that bring key figures vividly to life. It was released theatrically in Germany in June 2025.

Arthur Franck currently serves as chairman of the Finnish Documentary Guild.
